v1.0.0

What's Changed

We are delighted to announce the first major release of FerretDB!

FerretDB 1.0 GA includes all the core functionality of a document database required for production use. It has improved performance and stability over previous releases. Since our Beta release in January, we’ve added some notable features such as support for aggregation pipelines, indexes, and authentication. In the meantime, we've also pushed more queries to the backend, optimizing them for faster performance.

With FerretDB, you have an easy-to-use, developer-friendly, open-source, and production-ready replacement for MongoDB workloads.
